Asilver-copper alloy had a mass of 0.1264g. when the alloy was dissolved in nitric acid and the silver precipitated as silver chloride, the precipitate had a mass of 0.1375g. calculate the percent of silver in the alloy. for full credit, make sure you show your calculations.

The percent of silver in the alloy is 81.87%.

Explanation:

Mass of the alloy = 0.1264 g

Mass of silver chloride precipitate = 0.1375 g

Moles of silver chloride precipitate =

In 1 mole of silver chloride there are 1 mole of silver, then in 0.0009582 moles of silver chloride will ahve:

of silver

Mass of 0.0009582 moles of silver = 0.0009582 × 108 g/mol=0.1035 g

The percent of silver in the alloy:

the maximum mass of nh3 is nh3 in grams

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
